Jack Eichel had two goals and an assist, Noah Hanifin had a goal and an assist, and Logan Thompson made 26 saves for the Golden Knights (42-27-8), who have lost consecutive games after going 6-0-1 in their previous seven.
Vegas, which holds the second wild card from the Western Conference, remained one point back of the Los Angeles Kings for third in the Pacific.
“They’re a good team. There’s a reason that they are where they are in the standings,” Eichel said. “I thought there was stretches of the game where we controlled it, and there were moments where they obviously had momentum. It's frustrating. We had a lead and we don't get any points here, and points are important right now.”
Tomas Hertl had an assist and was minus-1 in 20:20 of ice time in his Golden Knights debut. He was playing his first game since being acquired from the San Jose Sharks on March 8 because of surgery he had on Feb. 12 to clean out loose cartilage in his left knee.
“First game after a long time and it wasn't bad, but I know I will be better,” Hertl said. “It's nice to be back, but I still got five more games to get all my legs.”
Eichel gave the Golden Knights a 1-0 lead with a power-play goal at 1:51 of the first period. He skated through the neutral zone and into the high slot before scoring glove side through the legs of defenseman Nikita Zadorov.
Eichel then made it 2-0 at 8:06, shooting into an open net from the bottom of the left circle off a cross-ice pass from Jonathan Marchessault.
“It was a test for us, I guess,” Miller said. “The way things have been going lately, for them to come out, get a couple on a couple of shots, we easily could have just sat back and said, ‘You know what, we'll try again next time.’ But it was a very serious and professional mindset on the bench, and it's nice to have the power play be timely for us to get us back in the game. We haven't had that in a while.”
